I need to bond a domestic gas pipe. Where the gas pipe enters the house it is buried in the wall and there is no access to the pipe, especially within 600mm of it entering the property.
The external gas meter cupboard is directly next to the external electricity meter cupboard. If i ran a conduit between the two (0.5 mtrs) could i bond the gas pipe in the meter cupboard on the consumer side of the meter?
Not sure if this would be ok so would like your thoughts.

Remember not to drill into the back of a resessed meter box as it must be gas tight in the point of view of the cavity wall, you must bring the cable in the front lip not via the back, which I suspect you will be doing anyway with a conduit run.

Thanks for the replies.
505diff, you pointed out that the gas meter box needs to be gas tight with regards to the cavity wall. If i conduit between the gas box and the electricity box via the front lip which is what i was intending to do then in theory i will need to ensure that the electricity box is gas tight. Do you agree and if so what do i need to seal it with?

if you are using 20mm conduit don't drill the 20mm hole through the inner plastic part of the gas box just the outer bit.then just drill a hole big enough for the cable on through. drill 20mm all way into electric box so that you can slip the conduit in before pushing back into gas box. seal ends and entries with a bit of silicone.

Geoff, Reg 544.1.2. If the meter is external (which it sounds like it is in this case) then the 600mm "rule" applies to the point of entry and nbot the meter union itself. However as you say the words "where practicable" are important, especially in interlay's case.

Yes, but you said above that the 600mm rule applies to the meter, not the point of entry which is correct if the meter is internal, but in this case the meter is external and so ideally it needs to be 600mm form the oint of entry to the building. Am i interpreting this wrong?

As interplay can't get at the point of entry he's going for the meter which is OK as it's as it's as close as reasonably practicable. Done this myself a few times.

Something to be careful of..
If you have an external gas meter remember that the reg says something like, "at the point of entry before any spurs."

It's quite common for there to be an external meter with the gas pipe coming in under the screed, teeing off to a gas fire, or cooker under the screed and then out of the screed up to the boiler. If this is the case you need to bond before the tee off section.
